A function or character string naming a function.

size

...

Other arguments of fun.

Details

clusterSplitSB splits seq into subsets,
with respect to size.
In size balancing, the problem is re-ordered from
largest to smallest, and then subsets are
determined by minimizing the total approximate processing time.
This splitting is deterministic (reproducible).

parLapplySB and parLapplySLB evaluates fun
on elements of x in parallel, similarly to
parLapply. parLapplySB
uses size balancing (via clusterSplitSB).
parLapplySLB uses size and load balancing.
This means that the problem is re-ordered from largest to smallest,
and then undeterministic load balancing
is used (see clusterApplyLB). If size is
correct, this is identical to size balancing.
This splitting is non-deterministic (might not be reproducible).

Value

clusterSplitSB returns a list of subsets
split with respect to size.

parLapplySB and parLapplySLB evaluates
fun on elements of x, and return a result
corresponding to x. Usually a list with results
returned by the cluster.
